Kevin Wilfong commented on HIVE-2937:
-------------------------------------
@Ashutosh
I dug deeper into the issue. I verified that the second HiveServerHandler does
exit the method, just via an exception rather than via the return. This
prevents the HiveServerHandler from being created. The test actually gets
stuck making the first execute call on the second HiveClient, presumably
because there is no handler on the other end of the connection to handle the
request, so it gets stuck waiting for a response.
I admit I am equally confused as to why this started showing up so frequently
recently. I had seen this problem a few times before, I had assumed it was
caused by running the tests twice on the same machine. Now however, I've run
into this problem every time I try to run tests, since yesterday.
As far as I can tell, there is no, and never was any logic to handle this
problem. So Navis's diff seems worth committing to fix that issue, and it is
at least a plus that it gets us around this issue, even if the root cause of
why this issue suddenly became so prominent is still unsolved.
I would like to commit this patch, unless you have any objections.
